Interpreting data from tables and graphs

Working scientifically

CCSS NGSS.SEP 4CCSS NGSS.SEP 5England: KS4 Working scientifically

Objective and success criteria

Students will: Interpreting data from tables and graphs.

  • I can answer questions on today's skill on my own, without help.
  • I can explain each step and say why it works.
  • I can check my answer and spot a mistake.

Before and after

Needs first: Reading tables and line graphs; Repeat readings, means and anomalies

Leads to: Analyse climate data: COâ‚‚ records and temperature trends

Materials: Simple equipment for a fair test, Results table template, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 5 min

  • Quick retrieval from earlier learning (Reading tables and line graphs; Repeat readings, means and anomalies). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. A group measured a pulse rate after exercise three times: 136, 139 and 138 bpm. What is the mean? Give your answer to 1 decimal place. → 137.7 bpmPrompt: Add the three readings.
  2. Water temperature (°C) → Time to dissolve (s) 10 → 67 10 → 59 30 → 51 20 → 43 25 → 35 What happens to “Time to dissolve (s)” as “Water temperature (°C)” increases? (it increases / it decreases / it goes up then down / it stays the same) → it decreasesPrompt: Read down the second column. Are the numbers getting bigger or smaller?
  3. A group measured the time for a ball to roll down a ramp three times: 34, 31 and 33 s. What is the mean? Give your answer to 1 decimal place. → 32.7 sPrompt: Add the three readings.

Hook · 5 min

  • Show a simple experiment with one thing changed and ask what makes it a fair test.
  • Share the objective: Interpreting data from tables and graphs. Read the success criteria together.

I do: model it · 10 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Study: Cooling coffee. Time (min) → Temperature (°C) 0 → 83 5 → 73 10 → 63 15 → 53 20 → 43 Estimate the value at 17.5, assuming the pattern between neighbouring points is a straight line.
  • Step 1: (53 + 43) Ă· 2 = 48
  • Step 2: So the answer is: 48
  • Answer: 48
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 10 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. Study: Stretching a spring. Force (N) → Extension (cm) 0 → 0 1 → 3 2 → 6 3 → 9 4 → 12 5 → 15 Estimate the value at 1.5, assuming the pattern between neighbouring points is a straight line. → 4.5Prompt: 1.5 lies halfway between 1 and 2.
  2. Study: Solubility of a salt in water. Temperature (°C) → Solubility (g per 100 g water) 0 → 12 20 → 20 40 → 28 60 → 36 80 → 44 How does “Solubility (g per 100 g water)” change as “Temperature (°C)” increases? (It increases to a maximum, then decreases. / It decreases steadily. / It stays about the same. / It increases steadily.) → It increases steadily.Prompt: Read the second column from top to bottom.

You do: independent practice · 10 min

  • Students work on the student sheet. Circulate and check the first two answers of every student early.
  • Students who finish: write a question of their own for a partner, with the answer.

The 8 questions are on the student sheet below, with answers in the key.

Exit ticket · 5 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. Study: Enzyme activity. Temperature (°C) → Reaction rate (units/min) 10 → 0 20 → 20 30 → 42 40 → 64 50 → 42 60 → 20 How does “Reaction rate (units/min)” change as “Temperature (°C)” increases? (It decreases steadily. / It increases steadily. / It stays about the same. / It increases to a maximum, then decreases.) → It increases to a maximum, then decreases.Prompt: Read the second column from top to bottom.
  2. Study: Light and pondweed. Distance from lamp (cm) → Bubbles per minute 10 → 49 20 → 43 30 → 37 40 → 31 50 → 25 At which value of “Distance from lamp (cm)” was the lowest value recorded? (10 / 30 / 40 / 50) → 50Prompt: Find the smallest number in the second column.

Watch out for

  • Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
  • Remembering facts without the reason: ask "why?" and "what is the evidence?"

Support and stretch

Support

  • Review first: Reading tables and line graphs.
  • Use concrete materials: simple equipment for a fair test.
  • Give the first step of each question, or a partly worked example to finish.
  • Pair with a confident partner for the guided practice.

Stretch

  • Move on to: Analyse climate data: COâ‚‚ records and temperature trends.
  • Explain a common mistake in writing and how to fix it.
  • Write a word problem that uses today's skill, then solve a partner's.
